Manufacturing method of actuator

A manufacturing method of an actuator, wherein the actuator comprises:

• a support body;
• a movable body, which is movable with respect to the support body;
• a viscoelastic member, which is adhesively bonded to one side member of a member structuring the support body and a member structuring the movable body by a first adhesive layer;
• and
• a magnetic drive circuit, structured to relatively move the movable body with respect to the support body;
• the manufacturing method comprising steps for adhesively bonding the viscoelastic member to the one side member by the first adhesive layer, wherein the steps comprises:
• a first step, in which the viscoelastic member is disposed on a side of one face of a first jig;
• a second step, in which the viscoelastic member and the one side member are overlapped with each other through an adhesive;
• a third step, in which the adhesive is hardened to adhesively bond the one side member and the viscoelastic member to each other by the first adhesive layer;
• and
• a fourth step, in which the first jig is separated from the viscoelastic member.
